321 stainless steel belt generally need high-temperature gasket materials for packaging materials, aerospace equipment, equipment and so on, because the 321 containing Ti, 304 high temperature resistant performance is superior, corrosion resistance is better than 304 more.
Tianjin Zhida stainless steel varieties Kai steel trading company operating, complete specifications, the main materials are: 304, 304L, 304F, 316L, 316F, 316, 301, 302, 303, 201, 202, 310, 310S, 321. Domestic materials in addition to operating the company's brand and business, Shanghai Baosteel, Pohang, Qingdao Krupp, Ningbo new, Guangzhou Lianzhong large steel materials, imported materials mainly include: Nippon Steel, Sumitomo, Pohang of South Korea, Italy, the major steel of high quality stainless steel material.

All kinds of stainless steel materials have different characteristics because of their different material content, so the corrosion resistance is also different. The following is a simple explanation of several commonly used materials:
304 stainless steel is one kind of universal, which is widely used to produce good performance (corrosion resistance and formability) equipment and parts.
301 stainless steel in the deformation, showing a clear working hardening phenomenon, is used to require a variety of high strength occasions. 302 stainless steel, in essence, is a variant of the 304 stainless steel with a higher carbon content, which can be obtained by cold rolling.
304L is a variant of the 304 stainless steel with a low carbon content, which is used for welding. The lower carbon content makes the carbide precipitates in the heat affected zone near the weld to the least, and the carbide precipitates may lead to intergranular corrosion in some environments.
304N is a nitrogen containing stainless steel, nitrogen is added to improve the strength of steel.
The company also supply similar products of the above products: 321 stainless steel band, 310S stainless steel strip, 316 stainless steel
